I HAVE HAD MY NEW 2009 R/T WITH AN AUTOMATIC FOR TWO DAYS NOW. MY ENGINE IS THE 5.7 HEMI AND IT IS SUPPOSED TO HAVE THE CYLINDER SHUTOFF FEATURE. ("MDS SYSTEM")

DOES ANYONE KNOW HOW I CAN TELL WHETHER THE SYSTEM IS ACTUALLY WORKING? IN 100 MILES OF DRIVING, I DO NOT FEEL ANYTHING DIFFERENT ABOUT THE ENGINE'S OPERATING CONDITION.

THE OWNER'S MANUAL INDICATES THAT THERE IS SUPPOSED TO BE A MESSAGE THAT SAYS: "FUEL SAVING" ON THE DRIVER INFORMATION SYSTEM ABOVE THE AVERAGE MPG DISPLAY. I HAVE YET TO SEE THIS FUEL SAVINGS MESSAGE APPEAR NO MATTER HOW I GENTLE I DRIVE THE CAR ON THE HIGHWAY.

DOES ANYONE KNOW HOW I CAN TELL IF THE MDS SYSTEM IS ACTUALLY WORKING????
